Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Set aside.

In a large mixing bowl, cream the softened butter, granulated sugar, and brown sugar together until light and fluffy, about 2-3 minutes.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. If desired, fold in the chocolate chips.

Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.

Bake for 10-12 minutes, or until the edges are set but the centers are still soft. Remove from the oven and let cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely.
